A, characteristics and USES
This machine is mainly used for thermal process in the production of coated sand mixing, work organization USES scraper and the rotor relative motion, make the material in the machine dish can mix in a very short time, make the sand coated, sand are of good quality and high efficiency, and the sand block has a good ability of fast break.

Three, the structure of the machine:
The whole machine is made up of drive system, working mechanism, lubrication system, the body and the discharging door, etc. As shown in figure 1.
1, the transmission system:
Transmission system includes main motor, rotor motor, reducer and transmitte narrow v-belt. As shown in figure 2. The main motor and the rotor motor installed on the bracket, both by the level of transmitte narrow v-belt couplet of (5 V - 10604) and reducer pulley connection, again through the level of cylindrical gear reduction. The main motor driven hollow shaft by hollow shaft driven in scraper. Rotor motor drives the rotor shaft, drive the rotor and scraper relative motion. Reducer is fixed below the sand mixer chassis, the cabinet is equipped with a magnetic oil plug is used to collect scrap iron in lubricating oil, in order to reduce the gear and bearing wear, prolong its service life.
2, work organization:
Work consists of scraper and the rotor. As shown in figure 3. Installed in the column on the set of two pieces of scraper and installed on the rotor of the three pieces of scraper, driven by the reducer output shaft relative motion. Two pieces of bottom scraper with hard alloy welded at the bottom of the knife block, in order to reduce wear and tear.
3, lubrication system:
Because of the speed reducer is only part of the bearing in lubricating oil, the machine adopts forced lubrication measures. The lubrication system by drop tank and is located in the motor on the drop tank, small gear oil pump, oil cylinder, travel switch, and the distribution of the reducer on body composition. Drop tank and the reducer connection with connectors. When the lubrication oil in the motor start drop tank after filtered, driven by pump pressure, small oil cylinder piston, make the trip switch, the main motor can start, distribution of lubricating oil at the same time the body and piping for lubrication. Failure occurs when the lubrication system, oil pressure is reduced, the piston under the action of the spring reset, travel switch off contact, signal control console is in failure, the main motor power, the machine stopped running.
